Abstract (en)

[origin: US2014203248A1] Disclosed are an OLED display structure and an OLED display device having the OLED display structure. The OLED display structure comprises: a substrate (10), and an OLED pixel layer (20), a beam splitting layer (5) and a circular polarizer layer (6) which are formed on the substrate (10) in sequence; the beam splitting layer (5) is adapted to divide a light beam into o-light and e-light, and to convert the o-light and the e-light into circularly polarized light which has the same polarization state as the circular polarizer layer (6); the circular polarizer layer (6) is adapted to allow passage of the circularly polarized light which has the same polarization state as it. With the display structure, the light transmittance is improved, and the pixel current of the OLED pixel layer (20) is reduced, and thereby energy is saved.
